摘    要:采用直接顶空进样法快速测定塑胶地垫中的有毒有害挥发性有机物的含量,利用气相色谱-质谱总离子流进行定性分析,选择离子流并用外标法进行定量分析,对顶空进样的平衡时间、平衡温度及色谱的分离条件分别做了优化,并进行了线性范围、回收率、精密度等试验。结果表明:9种目标化合物的线性范围为10~1000mg/L;相关系数为0.9960~0.9997;方法的检测低限为12.4~61.2ng/g;平均回收率为88.6%~112%;相对标准偏差小于8.6%。所建方法适用于塑胶地垫中苯、1-丁醇、甲苯等有毒有害挥发性有机物的测定。

关 键 词:直接顶空进样  塑胶地垫  有机挥发物  气相色谱-质谱法

Abstract:A rapid direct headspace injection method was employed for the determination of harmful volatile organic compounds. The qualitative and quantitative analysis were performed by total ion chromatogram and selected ion chromatogram respectively with GC-MS for the nine target compounds. The balance time and balance temperature of headspace injection and seperation conditions of chromatography were optimized. The tests of linearity range, recovery rate and precision were performed. The results show that the line...
